Couldn't resist snagging these two beautiful examples. I already have these guys in my collection, but the gorgeously silvered Carinus is an upgrade.
From left to right (my pics don't do them justice):
Carinus, AE Antoninianus, Antioch mint. IMP C M AVR CARINVS PF AVG, radiate, cuirassed bust right. / VIRTVS AVGG, Carinus standing right, holding sceptre, receiving Victory on globe from Carus standing left. Δ (Delta) in lower centre. Mintmark XXI.
Constantine I AE follis. 321-324 AD. CONSTANTINVS AVG, laureate head right. / DN CONSTANTINI MAX AVG around VOT XX star in three lines within wreath. Mintmark SMHB.
